Detection Method of Equivalent Leakage Inductance Cause by Transformer Winding Deformation Based on Finite Element Method

电力变压器在运行过程中绕组变形后会引起绕组漏电感值的变化,本文利用有限元仿真软件,对变压器的铁心及绕组进行建模,利用ANSYS软件计算了变压器漏电感值。

Leakage inductance is changed cause by winding deformation with transformers in operation. In this paper, we model transformer core and windings based on the finite element simu- lation software, and calculate the transformer leakage inductance by ANSYS.
